BACKGROUND

The present disclosure relates to the technical field of living goods, and particularly, to a portable binding device.

When binding bundled objects in open air, if gaps between the bundled objects are relatively large, and the bundled objects are of high hardness and elasticity, it may impossible for humans to tightly bind the objects with ropes or the like, resulting in the bundled objects not being compact and being bulky. However, existing binding devices are bulky, heavy, and inconvenient to carry, and thus may be impractical for many outdoor uses

SUMMARY

The present disclosure relates to a portable binding device, comprising a main shaft and a chain. Ratchets are fixed at each end of the main shaft and rotated in the same direction therewith. An outer ring of the ratchet is provided with a gear ring. A middle part of the main shaft is installed with a compression bar which is perpendicular to an axis of the main shaft. One end of the chain is connected to the middle part of the main shaft, and other end or the middle part of the chain is engaged with the gear ring.

In some embodiments, a positioning disc which is welded with a positioning plate, is arranged on the main shaft and adjacent to the ratchet.

In some embodiments, the positioning plate is provided with a chain positioning slot on a side far from the main shaft, and the chain positioning slot is in line with the gear ring.

In some embodiments, the positioning plate is provided with a chain tension skew plate located between the chain positioning slot and the gear ring.

In some embodiments, a positioning pin is provided on the main shaft and located between the positioning disc and the compression bar; the one end of the chain is provided with a positioning hole in which the positioning pin is inserted.

In some embodiments, the compression bar comprises a base portion and a rod portion, wherein the base portion is welded on the main shaft, and the rod portion is connected with the base portion by threaded connection.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic view of a portable binding device according to the present disclosure.

DETAILED DESCRIPTION

In order to enable the possible advantages of a binding device according to the present disclosure to be clear and comprehensible, example embodiments are further described in detail below, with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only explanatory, and are not intended to limit the scope of the present disclosure.

FIG. 1 is a schematic view of an example embodiment of a portable binding device according to the present disclosure. The present embodiment of a portable binding device comprises a main shaft 1 and a chain 11, wherein a ratchet 2 is fixed at each end of the main shaft 1. The ratchets 2 are rotated in the same direction as the main shaft 1, An outer ring of each ratchet 2 is provided with a gear ring 3. The middle part of the main shaft 1 is installed with a compression bar 4 which is perpendicular to the axis of the main shaft 1.

One end of the chain 11 is connected to the middle part of the main shaft 1, and the other end or the middle part of the chain 11 is engaged with the gear ring 3.

In one embodiment of the present invention, in order to make the device portable, the compression bar 4 may comprise a base portion 4-1 and a rod portion 4-2, wherein the base portion 4-1 is affixed to, such as welded on. the main shaft 1, and the rod portion 4-2 is connected with the base portion 4-1, for example, by a threaded connection. When not in use, the rod portion 4-2 may be removed from the base portion 4-1, so the binding device takes up less space and is more convenient for carrying.

In another embodiment, in order to make the device more portable, a positioning pin 10 is provided on the main shaft 1 and located between a positioning disc 5 and the compression bar 4. One end of the chain 11 is provided with a positioning hole in which the positioning pin 10 is inserted. When not in use, the chain 11 can be detached from the device and placed separately.

In another embodiment, in order to make it convenient for the user to put forth his strength when binding, the positioning disc 5 which is affixed to, for example by welding, with a positioning plate 6, is arranged on the main shaft 1 adjacent to the ratchet 2. When the compression bar 4 is pushed upwards, the chain 11 is tensioned tightly, and the positioning plate 6 can directly press on the bundled object to bear the force of the compression bar 4 when binding.

In another embodiment, in order to ensure the operational stability of the chain 11, the positioning plate 6 may be provided with a chain positioning slot 7 on the side far from the main shaft 1. The chain positioning slot 7 may be in line with the gear ring 3. The chain 11 is thus always in line with the gear ring 3 by reason of the positioning of the chain positioning slot 7 to prevent failures such as disengaging and dropping of the chain 11.

In another embodiment, in order to further ensure the operational stability of the chain 11, the positioning plate 6 may be provided with a chain tension skew plate 8 located between the chain positioning slot 7 and the gear ring 3. More specifically, the bottom of the chain tension skew plate 8 may be hingedly coupled to the positioning plate 6, and the chain tension skew plate 8 may be supported by a jackstay 9, or may be configured as a spring such that the chain tension skew plate 8 always jacks against the bottom of the chain to retain the chain in a tensioned state.

In the actual application of a device according to the present disclosure, one end of the chain 11 is connected to the main shaft 1, and the other end of the chain is passed through the bottom of the bundled object and then engaged with the gear ring 3, so as to drive the compression bar 4 to reciprocate. Due to the presence of the ratchets 2, the corresponding gear rings 3 can only rotate unidirectionally. By the unidirectional rotation of the gear rings 3, the chain 11 is continuously tightened, and finally binding the bundled object tightly. In addition, in the tensioned state, user can bind the bundled object with ropes or the like, and then pull up the chain from the gear ring 3 and retrieve the device.

The present invention is simple in structure, convenient for carrying, and has a good binding effect and high practicality.
